BlackBerry has filed a patent lawsuit (PDF) against Internet telephony firm Avaya. The dispute marks a turning point for Blackberry, which pushed into the Android market last year but has been struggling.
The patents include numbers 9,143,801 and 8,964,849, relating to “significance maps” for coding video data; number 8,116,739, describing methods of displaying messages; number 8,886,212, describing tracking location of mobile devices; number 8,688,439, relating to speech decoding and compression; number 7,440,561, describing integrating wireless phones into a PBX network; 8,554,218, describing call routing methods; and number 7,372,961, a method of generating a cryptographic public key.
The patents have various original filing dates, ranging from 2011 back to 1998.
The BlackBerry complaint states that the company notified Avaya of its alleged infringement of those specific patents in a letter dated December 17, 2015.
